Honey, it's too hot for hot tools! Embrace these easy, zero-effort summer hairstyles. They work beautifully with your natural texture, so you can take a couple of days off.

THE BARELY DONE BRAID

THE BARELY DONE BRAID

There's nothing kidlike about this look--except how unbelievably easy it is to create. In fact, you can do it on wet hair without a drop of product (unless you have fine hair, in which case a dollop of mousse will give it some hold). While your hair is damp, finger-comb it back off your face and, starting at the crown, make a tight braid, shifting it to one side as you go. Wrap an elastic around the end, then gently tug a few spots along the sides of the braid and your hairline to loosen some pieces. "The softer and more imperfect the style is, the sexier and more grown-up it looks," says Tresemmé celebrity hairstylist John D., who has worked with Jennifer Garner. (If you're good at this stuff, start out by making a small French braid on one side of the front of your hair, as pictured here. Then tuck the end into the main braid.) When the sun goes down, unravel your hair and--ta da!--instant waves.

THE EFFORTLESS TWIST

THE EFFORTLESS TWIST

Hair gone crazy in the heat? "A bun is the quickest way to look instantly polished," says celebrity hairstylist Tim Rogers, creative director of Living Proof hair care, who has worked with Kate Hudson. But a slick bun can look harsh. To make it soft, use your fingers instead of a brush to gather your hair at the back of your head. Wind it into a chignon (if you have long, heavy hair, secure it in a ponytail first), then use U-shaped hairpins--not bobby pins, which don't hold as well--to pin it down at the top, bottom, and each side of the twist (try Sta-Rite Hair Pins, $2.29). Don't sweat any fuzzies around your hairline. "They add to the romantic feeling of the look," Rogers says. Bonus move: When headed to the pool or beach, saturate your hair with a deep treatment like Biolage Fortethérapie Intensive Strengthening Masque, $16, then twist it up. "The mask acts as a barrier, protecting your hair from chlorine and salt water," says Rogers. "Plus, the sun's heat helps the nourishing ingredients penetrate, so when you rinse it out, your hair will be incredibly shiny."
